Single-Wall Connectors
Complete Seal Fittings 6” to 24” Diameter Complete Seal fittings are manufactured from galvanized steel meeting spec ASTM A-653 (Lockforming quality). They feature a double legged EPDM gasket which creates a virtually airtight connection when slipped into spiral pipe. The gasket is mechanically attached to the fitting with a 180 degree hemmed edge. This hem gives added rigidity to the fittings, ensures that the gasket will never slip out of place and makes a safe rounded edge for the installer. *Complete Seal is currently available on Galvanized Fittings only.
E-Z Flange with Barrel Clamp 26” to 96” Diameter The E-Z flange with barrel clamp can be factory installed or shipped loose for field installation. A set consists of two E-Z flanges and one barrel clamp. For field installation the installer attaches the E-Z flange to the pipe and fittings. Next the installer applies the gasket to one flange, mates the two flanges together and attaches the barrel clamp. Sheet Metal Connectors can also install E-Z flanges. Flanges are spot welded and internally sealed on all ends of the spiral pipe and fittings.
E-Z Flange Jr. with Barrel Clamp 6” to 24” Diameter The E-Z flange jr. is a 5/8” flange turned out 90° on each end of the spiral pipe and fittings. The installer applies a gasket on one flange, mates the two flanges together, and attaches the barrel clamp. For field cuts a 5/8” flanged sleeve is available. Trim the spiral pipe to the measured length and attach the sleeve.
Standard Spiral Pipe Connector Pipe to Pipe connections are made by using a fitting size coupling that slips inside the mating pipe sections. A stop bead runs around the middle of the coupling to center the coupling in the connection. Secure the connection by installing sheet metal screws through the outer shell of the duct, 1/2 inch from the stop bead.
Companion Angle Rings Pressed and Rolled Companion angle rings are for end connections whenever a smooth interior surface or intermediate stiffening is required. Rings are manufactured from mild steel. Companion angle rings can be factory installed or shipped loose. Companion angle rings can be attached by solid weld, tack weld, or van stone connection. See companion angle ring size chart on page 20.
